A review will only tend to occur when your raise increases your income a certain amount. 15% seems to be pretty standard, but it may be different in your state. So, no - it won't be recalculated for every penny.
Yes, OP, please call your child support enforcement office to see what the number is in your state.
Furthermore, it's not automatic in most states. In some states, you don't even need to notify CSE or the other party of your raise. And in many (if not most) states, the CSE modification is not automatic-it needs to be requested by one party or the other.
Here are the rules:

However, since your questions is essentially a procedural one, I would contact the child support enforcement office to ask them how it works.
ETA: also check your existing child support and/or divorce and/or legal separation order. Even if CSE doesn't require you to report, there might be something in your court order that says that you must notify the other party of raises. It's not that common, but it might be there.
